Creators Syndicate, another major player, requests at least four weeks of dailies, and no more than six weeks' worth and two Sunday strips.

Most comic strip artists draw their dailies in a 13" wide by 4" tall format. For a single-panel cartoon, the most common size is a 7" square. However, any size can work as long as the height and width follow those general proportions. All samples should be photocopies, not original work, and submitted in black ink on white paper.

King Feature will generally respond within eight to 12 weeks if it's interested in seeing more work. If you don't get a response within that timeframe, the cartoon isn't something that will work for the company, Burford says. Including a self-addressed stamped envelope will facilitate a response.

Should you be one of the lucky cartoonists contacted for further development or a contract, a syndicate will work with you to package, edit and promote your strip to newspapers and other outlets in the country or across the world.

Marianne Sugawara, Creators Syndicate's vice president of operations, advises cartoonists that the writing - not just the illustrations - is very important.

"It's harder to find a strong writer than a good illustrator," says Sugawars. "There are a lot of very good artists out there. A lot of it is the writing."

Both Sugawara and Burford say it's difficult to predict success.

"It's incredibly difficult to get a new comic strip to catch on," Burford says. "It's certainly not a formula. If it were, all the syndicates would be bottling it."

By the way, all the major syndicates post submission guidelines on their websites, and encourage you to read them before you mail in your work.
